According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children. The developing brain, the report says, is particularly【C1】______to the toxic effects of certain chemicals these products may contain, and the damage they cause can be【C2】______.
The official policy, however, is still evolving. Health and environmental【C3】______have long urged U. S. government agencies to【C4】______the use of some of the 11 chemicals the report cites and called for more studies on their long-term effects. In 2001, for example, the Environmental Protection Agency【C5】______the type and amount of lead that could be present in paint and soil in homes and child-care【C6】______, after concerns were raised about lead poisoning. The agency is now【C7】______the toxic effects of some of the chemicals in the latest report.
But the threshold for regulation is high. Because children’s brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it’s tough to pin them on exposure to specific chemicals with solid【C8】______evidence, which is what the EPA requires. Even the Harvard study did not prove a direct【C9】______but noted strong associations between exposure and risk of behavioral issues.
Nonetheless, it’s smart to【C10】______caution. While it may be impossible to prevent kids from drinking tap water that may contain trace amounts of chemicals, keeping kids away from lawns recently sprayed with chemicals and freshly dry-cleaned clothes can’t hurt. A)advocates I)particles
B)compact J)permanent
C)correlation K)restricted
D)exercise L)simulating
E)faculties M)statistical
F)interaction N)tighten
G)investigating O)vulnerable
H)overwhelmed
【C9】
选项
答案
C
解析
该空格位于不定冠词a和形容词direct之后,应填入可数名词的单数形式,分析上下文可知,此处表达的意义为“暴露于有害的化学物质之下与患行为方面疾病风险之间存在直接相关性”。故答案为C)correlation“相关,关联”。备选项中名词还剩下interaction和particles,均不符合上下文语义,故排除。
